Canon 200D versus Sony A7

The Canon EOS 200D (called Canon SL2 in some regions) and the Sony Alpha A7 are two digital cameras that were officially introduced, respectively, in June 2017 and October 2013. The 200D is a DSLR, while the A7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (200D) and a full frame sensor. Both cameras offer a resolution of 24 megapixel.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 200D and the Sony A7. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the 200D – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 is somewhat larger (5 percent) than the Canon 200D. Moreover, the A7 is slightly heavier (5 percent) than the 200D. It is noteworthy in this context that the A7 is splash and dust-proof, while the 200D does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (200D) and the Sony FE Lens Catalog (A7). Mirrorless cameras, such as the A7, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 200D was launched at a markedly lower price (by 68 percent) than the A7, which puts it into a different market segment. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 200D features an APS-C sensor and the Sony A7 a full frame sensor. The sensor area in the A7 is 158 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

Even though the A7 has a larger sensor, both cameras offer the same resolution of 24 megapixel. This implies that the A7 has a lower pixel density and larger individual pixels (with a pixel pitch of 5.97μm versus 3.72μm for the 200D), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 200D is much more recent (by 3 years and 8 months) than the A7, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the A7 offers substantially better image quality than the 200D (overall score 11 points higher). The advantage is based on 1.2 bits higher color depth, 0.8 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7 has an electronic viewfinder (2400k dots), while the 200D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon 200D and Sony A7 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 200D is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the A7 was succeeded by the Sony A7 II.

Summary

So how do things add up? Is there a clear favorite between the Canon 200D and the Canon 200D? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Advantages of the Canon EOS 200D:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Longer lasting: Can take more shots (650 versus 340) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (68 percent cheaper at launch).
  • More modern: Reflects 3 years and 8 months of technical progress since the A7 launch.

Arguments in favor of the Sony Alpha A7:

  • Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More heavily discounted: Has been around for much longer (launched in October 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the A7 emerges as the winner of the match-up (10 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

200D 07:10 A7

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 200D or the A7. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
